CLARIFIER.

Application filed April 6, 1925. Serial No. 20,922.

My invention relates to clarifiers and the As clearly shown in Fig. 1 of the drawprincipal objects of the invention are to ings, the conduits fit one within the provide a vessel with a plurality of shelves other thus forming a continuous passagesuperimposed one upon the other in spaced way. The lowermost shelf 7 is supported relation by means of connecting conduits above the bottom of the vessel 5 by legs 11 that form a continuous passageway from the resting thereon and in such position that the bottom to the top of the vessel whereby the lower end of its conduit 10 is at a distance clarified liquid may be siphoned oil after above the bottom of the vessel. A. siphon 12 the sediment has collected on the shelves. may extend through the cover 6 and fits 9 Further objects are to provide a clarifier by snugly within the uppermost conduit. 6
